VLC randomly goes to fullscreen while in docked playlist view ( Possible bug? )

[pottsdie]

View -> Docked Playlist

Playlist -> expand any playlist ->Start playing
My Music -> expand any folder - Start playing

Result: VLC randomly decides to exit playlist view sometimes and switch to fullscreen view without any input telling it to do so. It doesn't always do this. Just when reaching certain files, but not always on the same file so it's pretty random.

Bug or feature? Is there an option to tell VLC to never exist docked playlist view unless I specifically do it myself?
